I only agree with this partially. If you have a useless, uneducated POS go to prison for a first time offense, which would mean only a few years and don't teach him how to live in society (because his parents didn't) you can expect him to return to prison soon. If they are going to be there, make them learn something.

How? I don't have a clue.

I just finished reading Orange is the New Black and it touches on this a lot. If you don't prepare the cons for life on the outside then you'll be seeing them back inside soon enough.
